"iriy invention relates to door` mechanism tor-'railwaycars and isespecially suitable for Vtion for dampeapplication to hopper cars,although it may advantageously be employed on" cars ot' other types. l I

The principal object of the invention is to provide simple and reliablemeans, in ad tion to the usual doin" supporting mechani. n, which servesto n the discharge ont` lading,

such as ballast and the like, trom the car,

Another objectot the invention is to provide inii'iroved means forlocking' the inorahle member of the-door mechanism in door supportingposition. l

Figure 3 is a fragmentaryview, parts being; in section, taken on a linecorresponding' to line 3*:3, Figure Q. 'Q '1 1 VVhile the drawingsillustrate a single hop-v per andlthe adjacent edge of the coactingdoor, itis to he understood that theconstrucappear vtion is preteral vduplicatedon the oppositesident 'the car and tliatthe rdoor illustratedis hutoneot a pair'otI doors connected by a spreader for stiii'enii'igmember so' as to swing as one.

ln the drawings, l indicates the sloping' side sheet ot the hopper and 2is the swing# ing door for closing the discharge opening` thereof'. Thedoor may be secured to thel car body by the usual hinges, not shown, soasvto swing to open position under the iniiuence oi gravity. V

Mounted upon the outer face of the door adjacent the Vitree edge thereofis Va door spreader or stili'ening member B'which may conveniently be ofVchannel-shape, one ot the legs 4 of the channel beingI secured to thedoor and its WebV 5 projecting outwardly therefrom. Rigid With the dooris an arin riifets'? and S being employed i'or respectively attaching'the lattertothe dooi' andV the outwar'ly projectingiveb of the stitlener. To permit the arm G to `project"outwardly beyond the side edge of'the door, it may advantageouslybe offset as at 9 to pass around themarginal outwardly projecting flange 10 of the latter: Adjacent itsdising member 1 1, the latter constituting a seat i'or thev dooi' andaffording means preventinl the escape of line lading and the likeV fromthe car. Pivot-ally connected to the hopper is ahook vmember 12, thehoolrbeing' VrashL4 ioned with a plurality oi ledges 13 'and '14 rcselei'ational Gli iao

spectively adapted to engage the upstanding fiange of the door arm tosupport the door in a position of partial closure and in a posi tion offinal closure. A filler casting or member 16 is preferably fashionedwith a plate portion 17 and with apertured lugs or bosseslS, 1S) and 20,respectively, which project inwardly into engagement with adjacentportions of the hopper.

Over-lying the outer face of the hook 12 is a cover plate or bracket 21,the latter being likewise provided with inwardly projecting aperturedbosses or lugs 22, 23 and 24 respectively. rlhese bosses engage theouter face of the plate portion 1T of the filler castingV 1G to spacethe cover plate outwardly from the hoek 12. The corresponding bosses ofthe filler casting and cover plate receive rivets 25 which serve torigidly connect these members to the side sheet 1 of the hopper and toeach other. The inwardly projecting boss 22 affords a pivotal supportfor the hook 12, the pivoted end of the hook being enlarged as at 26 toprevent longitudinal movement thereof on its pivotal support.

lntcrposed between the cover plate 21 and the filler member 1G is apivoted auxiliary hook or member 2.7, the boss 23 serving as a pivotalsupport therefor. Adjacent its pivoted end the hook may advantageouslybe fashioned with an enlarged portion 2S which projects therefrom in theopposite direction from which the enlarged end 26 projects from the maindoor supporting hook 12, thus enabling the two hooks to operate inspaced and preferably parallel planes; rllhe outer end of the auxiliaryhook 26 is fash ioned with a ledge 29, having a depression 30 forcooperating with the-lug or projection 31 formed on the upper portion ofthe iiange 15 of the door arm, the depression and lug respectivelyfunctioning to prevent the auxiliary hook from being thrown or kickedsuddenly upward by it engaging the door arm when the door is releasedLerom its supporting mechanism and permitted lo swing toward openposition.

A locking device or cam may be employed for maintainingl the hook 12 indoor supporting position, the device being rotatable about the inwardlyprojecting boss 23 of the cover plate 21.

lnstead of forming the locking device 32 as a sepa `ate member it mayadvantageously be integrally formed upon the pivoted end of theauxiliary hook 27. In this manner it will be perceived that upon therotation of the auxiliary hook into an inoperative position, asillustrated in Figure 1, the cam 32 is caused to rotate into lockingengagement with the door supporting hook 12. rlhe cam is preferablyfashioned with an eccentric surface 33 having a plurality oi spacedpro'tuberances or projections 3aand 35, respectively; the latter, beingformed on the rveaeee eccentric surface 33, are disposed at unequaldistances from the axis of rotation of the cam and they are so arrangedthat, when in engagement with the hook 12, they are disposed on oppositesides of the line AHA (see Fig. 3) passingthrough the axis of thc camand normal to the cooperating face of the hook. rEhe protuberance 3stwhich moves beyond the normal line A-A performs, in effect, the entirelocking function of the cam 32; while the protuberance 35 merely servesa stop, upon engaging the upper surface of the hook 12,V to preventfurther locking rotation of the cam. The protuberances being disposed inthe manner indicated effectively prevent the cam from accidentallyrotating out of engagement with the hook, since a further lockingrotation of the hook 12 will be necessary before the pri'ituberance 34may pass from engagement therewith. Then the door is supported in afinally closed position, as shown in Figure 1, the cam 32 is rotated incounter-clockwise direction until both f the protuberances are inengagement with the upper surface of the hook, there being` sutiicientinherent resiliency and flexibility in 'the parts to insure that thehook 12 will move upwardly into engagement with the protuberanceElllafter the latte-r passes, in its locking movement, beyond Vthenormal line The auxiliary hook 27 is primarily employed for arrestingopening movement of the door after the latter has been released from itsdoor supporting mechanism, so as to maintain the door in a position fordampening the discharge of lading, such as ballast and the like. J

When it is desired to support the door in a position such that thedischarge lading may be dampened or checked, the auxiliary hook 2T isrotated in a clockwise direction from the position indicated in Figure 1into engagement with the upper marginal edge of the flange 15 of thedoor arm. The cam being rigid with the auxiliary hook, rotation of thelatter causes an unlocking rotation of the cam, thus enabling the hook12 to be disengaged from the arm 6 permitting the door to swing open.Since the ledge of the auxi liary hook is disposed in the path ofmovement of the door arm, it will arrest opening movement of the doorand thereby maintain the door in a position for dampening the lading asit fiows from the discharge openingl of the hopper. Should it be desiredto permit the door to swing entirely open from a fully closed position,the auxiliary hook 2T is rotated as before described until it engageswith a. removable pin, bar, stick or the like, (not shown) which isadapted to be inserted in the opening 36 formed in the reinforcinghopper flange 11. The parts are so proportioned that when theauxiliary hook is supported in this elevated position, the

cam assumes 'a position enabling an `unlocking movement of the ,hook`and a subsequent swinging movement of the door into a` fully openposition. To close Vthe door, the latterl is swung into a positionpermitting theledge fl?) of the hook to engagethe flange 15 of the doorarm to thereby maintain the door inv a partial position of closure. Asis usual in door supportingmechanisms of this character, the cover plate21 is provided with an aperturedl eXtensionB,constituting a fuln Crumfor a removable bar, not shown, the latter, by cooperating with a.portion of the door arm, maybe operated to force the door toa positionenabling the ledge Mot the hook to engage flange 15 oiE the door arm andthus supportA the door in a position oi final closure. i v
